lApplication December 24, 1943, Serial No. 515,568 31 claims. (ci. ssn-516.2.)

The present invention relates to improvements in means for mounting av motion picture projector. More particularly this'structure contemplates a mounting structure whereby the projector is effectively housed for ready transportation from one location to another and when it is desired to use the apparatus the projector is readily accessible for threading the iilm strip thereon and for operating the same for the projection of motion pictures and for the reproduction of sound. The mounting is constructed in a simple manner which renders it possible for the operator to have ready access to the various parts of the motion picture and sound elements without the necessity of having to remove the projector or operation, and dependability of such a mount'- ing.

Another principal object of the invention is to s provide a mounting that is novel in its construction and in the arrangement of its parts- The present structure is made of sturdy parts that are designed to withstand severe usage, and it is comparatively economicalto produce so that it will not materially increase the cost of the pro- '1 jector outfit.

Additional objects, aims and advantages ofthe invention contemplated herein will be apparent to persons who are skilled in the art after the construction and Voperation of the mounting for a motion picture and sound projector is understood from the within description.

It is preferred to accomplish the numerous objects of this invention and to practice the same in substantially the mannerl hereinafter fully described and as more particularly pointed out in the appended claims, reference being made herein to the accompanyingv drawings that form a part of this specification.

In the drawings:

Figure i is a longitudinalv side elevation ofthe structure contemplated herein with the hinged closure member in opened position..

Figure 2 is a vertical elevation looking at the right hand end of Figure 1 showing the complete structure in closed position for transportation.

Figure 3 is a vertical elevation looking` at the right hand or projection end of the structure shown in Figure I with ther` projector unit in a.

tilted position to permit access to the instrumentalities on the back of the same.

Figure 4 is an end elevation similar to Figure 2 showing the body and mount tilted back for access to: the driving motor and to certain portions of the sound reproducing apparatus.

The drawingsv are to be understood as being more or less of a schematic character for the purpose of4 disclosing a typical or preferred form of the improvements contemplated herein, and in these drawings like referencecharacters are used to identify the same parts wherever they appear inthe different views. v l

The structure contemplated herein comprises a housingembodying a main body section A, and top and bottom sections B and Cv respectively, all of said. sections being of hollow rectangular shape. The `top section B is provided l'with a carrying handle D on its upper wall, and it is removably secured to the main intermediate ksection A by releasable latch devices E of any convenient construction. The bottom section C is open at its top and along its vertical rear wall it is connected by hinges F to the adjacent lower edge of the rear wall of the main section A. This bottom section hasits front wall detachably connected to the lower edge of the front wall of the main section A by releasable latch devices G.

The purpose Vof the top section B is to provide" ready storage for the reel-mount arms and other mechanical accessories (which are not shown) and it is adapted tombe unlatched and removed when the motion picture projector apparatus and sound reproducer are in use. The bottom section C provides facilities for accommodating the electric motor 5 that actuates the film moving mechanism; .and the fan housing 6 for cooling the motor. Also, the photo-electric cell 1 and the ampli'er unit 8 are supported on a suitable platform 9 that is secured preferably to the lower wall of this section'C of the housing. The cell 1 and the ampliiier unit 8 are located towards one end of the bottom section C and project up into the lower portion of the main section A, and the motor 5 and fan housing 6 are located towards the other end of the housing so that these elements are separated from each other a sufficient distance and will not interfere or come into contact.

The motor 5 and fan housing 6 are attached tothe underneath side of a normally horizontal movable base I0 that supports the standard' memments I3 that movably` connect said base to the housing so that it is normally in a horizontal plane above the tops of the exciter lamp 1 and amplifier 8.

The front wall of the housing is formed in two parts, lower member I4 being a permanent portion of the housing and terminates at the horizontal plane of the base I of the standard that is hinged thereto. The remaining or major portion I5 of the front wall is connected by hinges I6 to the upper edge of the short lower wall I4. The forward and rear walls I1 and I8 are severed on an oblique line I8 extending upwardly from the plane of the hinges I6 to near the center of width of the housing and the forward triangular portions I1a are attached to the vertical edges of the hinged front wall member I5 so that when this assembly is swung outward and down, as shown in Figure 3, the side of the projector standard that faces the operator will be open for free access thereto for threading the film and for other operations. Should access be desired to `the instrumentalities at the back of the standard II the entire assembly, including the standard, may be tilted outward in the manner illustrated in Figure 3. Since the motor 5 and fan housing 6 are a part of this unitary assembly, it is not necessary to dismount the drive belt that connects the motor to the iilm actuating devices.

'I'he end wall of the housing that is in front of the projector unit is provided with a window W that is intersected by the oblique dividing line I9. This window W is axially alined with the projection lens L and may be closed by a suitable element i1' desired.

The transverse wall I2 of the standard car ries the projection lens L in front of the alined light aperture I8a and back of the aperture is the lamp I 9 that provides the illumination for the f projector. Also mounted on the back of the transverse wall I2 the usual shutter (not shown) and the intermittent film feed devices 20, that -are merely schematically illustrated, that are driven in any suitable manner by an operative connection with the motor 5.

The continuously rotatable film engaging sprockets 2| and 22 are disposed on the front of the longitudinal wall I I of the projector standard and have their spindles projecting through to the back of said wall where they are connected to the respective gears 23--24 that is meshed with a driving gear 25 that derives its motion in any suitable manner from the motor so that the sprockets 2| and 22 are rotated in unison. The film, after leaving the usual guide or track that is back ofthe lens L, is led around a drum 26 which houses the sound optics and slit assembly in alinement above the exciter lamp 1 in the lower section C of the cabinet. A continuously rotatable sprocket 21 withdraws the film from the `drum 26, the said sprocket having its spindle projected through the wall II of the standard where a gear 28 in mesh with gear 25 is fastened to it for driving sprocket 21 in synchronized relation with respect to the sprockets -2I and 22. The sound reproducing instrumentalities of the projector are electrically connected'to a dynamic loud speaker 29 positioned at a screened opening in the back wall of the main section of the housing where it will be convenient for access when the projector assembly unit carried by the base l0 is tilted in the manner shown in Figure 3.

While this invention has been described in detail in its present preferred form or embodiment, it will be apparent to persons skilled in the art, after understanding the improvements, that various changes and modifications may be made therein without departing from the spirit or scope thereof. It is aimed in the appended claims to cover all such changes and modifications of the structure that is contemplated herein.
